What Is Domain Knowledge?

To answer the question "What is domain knowledge?", domain knowledge is the specialised understanding of a particular activity, discipline or industry acquired through formal or informal training and field experience. People with domain knowledge tend to have different and more focused skills than those with more general knowledge. For example, a cardiac surgeon has more specialised cardiac knowledge and surgical skills than a general practitioner. While professionals in specific fields can have domain knowledge of their subjects, they can also be well-informed about topics outside their industry. For example, a software developer may have financial expertise and use it to create financial applications.

Such knowledge is not reserved only for professional specialisations but can also cover personal interests, hobbies and passions. For example, you can have domain expertise in education, health care, data science, engineering, architecture, gardening and art.

How To Improve Domain Knowledge

You can use the following suggestions to improve your domain knowledge and become a more competitive candidate:

It might help to create a list of the subjects you want to know about and add to it over time. You are likely to come across many more topics to explore as you conduct your research, even some that you may not have known about earlier.

While researching information online, you can note the websites you visit and their sources. It can help you keep track of the information you collect and where you acquired it.

2. Take relevant courses

Aside from researching information online, you can consider taking formal educational courses to expand your knowledge of a particular industry. There are many online and offline specialised courses that you can take after completing your Secondary School Certificate (Class 10) or Higher Secondary Certificate (Class 12). You can sign up for certificate, diploma, bachelor's degree, master's degree or doctorate programmes in your chosen specialisation. Having formal credentials can give you more legitimacy in the eyes of prospective employers and increase the job opportunities available to you.

3. Interview industry experts

You can also improve your domain knowledge by interviewing verified subject experts in the industry. Since these experts generally have busy schedules, it might be best to reach out to them via email first and then arrange for a phone, video or in-person interview. Consider preparing a list of topics to discuss and questions to ask during the interview. It is also advisable to record the interview so that you do not miss any important points.

Be mindful of the expert's time and avoid deviating too much from the agreed topic. Remember to thank them at the end of the interview and ask for their permission in writing to use the information you gather from the interview.

4. Network with industry professionals

By networking with established and upcoming industry professionals, you can stay apprised of current developments in the field and update your domain knowledge. Attending professional events and conferences can bring you in contact with industry professionals, but you can also participate in workshops and training programmes. These meetings with the industry specialists can build your knowledge, and they may also result in professional opportunities for you.

5. Understand the industry terminology

Understanding and mastering the specific terminology of your industry is an important part of improving your domain knowledge. You can create a list of the jargon, terms and acronyms that are in use in your industry and write down what each means. If you do not know the meaning, you can look it up online, ask your colleagues or consult with industry experts.

Some terminologies may be industry-specific, while others might be usable across different domains. You may also encounter the internal language of companies where insiders may use coded terms, complex words and jargon that outsiders cannot easily comprehend.

6. Learn about business and operational dynamics

Every domain has its specific business and operational dynamics. It is essential to familiarise yourself with these to develop domain knowledge expertise. You can learn how to define business goals and understand the business ecosystem. You can find out how to carry out business operations, plan business actions and monitor performance metrics.

7. Get informed about industry challenges, risks and opportunities

You can learn about the factors that affect a specific industry and their negative and positive impacts. You can find out about the market and economic risks to the companies in the sector. Additionally, you can get informed about the available market opportunities. Having this information can help you develop effective strategies to counter challenges, minimise risks and find opportunities.

8. Use the industry products or services

You can broaden your domain knowledge by using the products or services of your industry and getting acquainted with their specific characteristics. As you use the products and services, you start to understand why the product designers designed them as they did, how they intend people to use them and how people actually use them. When you view them from the perspective of the customers, you might realise that there are things you could do to improve their features.

Personal use may not be possible for some products or services. In this case, you can study how customers use them. You can also take surveys to ask people about how they use them. Additionally, you can get informational data from a sales team. They may have research and marketing materials aimed towards your specific industry.

9. Document and organise your research

You can retain more from your domain knowledge research if you properly document, categorise and organise all the information you can gather from various sources. You can use spreadsheets for this purpose since they can store large amounts of data and are easily searchable. It is also easy to access the spreadsheets with different digital devices at any time from any location and share them with people at various locations.

Having all the information available in one place can facilitate data analysis work and enable you to learn more about your industry. You can continue to add new information as you come across it to the spreadsheets. You can conduct data backups to secure the information and also take printouts.

10. Create a detailed map of the system

After you have enough knowledge about a specific domain, you can create a detailed map of its entire industrial ecosystem. That can enable you to look at the big picture and gain a clearer perspective of the whole system. You can then understand the domain best practices and the different factors that are responsible for driving business success or hindering it. You can also find out how the company's products and services fit into the industry ecosystem. That may help you focus on the important issues and determine the changes you can make to improve things for the better.
